Specification of Letters Patent.

Application filed April 16, 1912. Serial n es1,oec.-

To all whom it may concern:

Be it known that 1," CHARLES G. OVER- MYER, a. citizen of the United States, residing at Hartford City, in the count-y of Blackford and State of Indiana, have invented certain new and useful Improvements in Reversible Pots, of which the following is a specification, reference being had therein to the accompanying drawing.

This invention relatesto reversible pots to be used in the manufacture of window glass, and has for its object the production. of an efficient pot which may be easily reversed within the furnace.

Another object of this invent-ion is the production of an efficient furnace, wherein the pot may he so convenienz'ly held as to be readily set into and removed therefrom, and also readily reversed within the furnace.

Still another object of this invention. is the production of an efficient furnace which is provided with a top, which top will normally beheld in a closed position, and may be easily and quickly drawn upwardly while With these and other objects in view, this invention consists of certain novel construcl-lOIlS, combinations, and arrangements of parts, as will be hereinafter fully described and'claimed.

In the drawings :Figure 1 is a perspective view of the furnace showing the pot in position. Fig. 2 is a perspective view of the furnace showing the pot in a position where the same is being set into or has just been removed from the furnace. Fig. 3 is a longitudinal sectional view of the furnace showing the pot therein.- Fig. t is a central transverse section through the furnace, and pots.

Referring to the drawings by numerals, 1 designates the furnace which maybe of a rectangular structure provided with an open upper end within WlllCll 1s placed, near one end thereof, a filling block 2. This filling block is formed with the furnace so as to fit snugly around the pot when the pot is placed within the furnace. The lnner face is, of course, formed concave so as to receive the rounded end of the pot, and the sides of the furnace are formed so as to fit snugly around the pot as illustrated in the drawing. A door 4 is lunged to the upper end of the body 1 upon the side plates 5. This door-dis provided with a weighted bar 6 wh ch acts as a'counterbalancc therefor. A cleat 7 is carried on one end of the box 1 and this cleat 7 carries a plate 8, which plate 8 spaced from the cleat 7 by means of the spacing block 9. This plate .8 acts as a g t'iidev for the operating lever 10, which operating lever is pivotaliy secured to the bloc 11 carried by the end of the-box 1. l A chal 12 connects the lever 10 to the ham 6 of thedoor 4;, and it will be seen that the door may be raised and lowered. through the A locking pin 18 is carried b the elect 7, and pro ects fromthe end o the body 1, and the lever'lO- may be hooked under. the

extending position so that the pots may be freely reversed or rotated, and set into and removed from the furnace orbody l. f

The box 1 or furnace is provided with notches 14, and dove-tail" filler blocks 15 the notches above the shafts 16 of the pots to prevent the flame from coming throu h or overt-he pots, The plates 17 are mo ded in the block 15 carried by the sockets 14: upon each side thereof andconstitute means shafts l6. y i

The pot 17 is provided with a shoulder by forms the top of the pot 19, and a bottom 20 for the other pot. The upper face of the pot carries a pot 21, and it will, therefore, be seen that the pocketwill, be formed in such a position as to allow the. pocket to come in its correct position when the pot is reversed within the furnace. The pot 17 is provided upon each side witha socket 22, within which socket 22 is placed a metallic lining 23. This lining .23 extends over the side edges of the pot and carries an auxiliary pocket 24 which constitutes meansv for allowing the lifting hooks 25 to engage the same whereby the'pots may be conveniently set into or-removed from the furnace. The hooks 25'arep'rovided with inwardly extending ends as fitting into the sockets 24, above mentioned. The pots 17 may be made of fire clay or other suitable material which will not be affected by the heat'l The furnace is placed in such a position as pin 13 for holding the top in its upwardly.

for holding the pots in engagement with the upon both the top and bottom of the pct;

medium of the lever 11, when so desired.

adapted to fit in the sockets 14 forfilling 18 upon itsiupper and lower face, and therea furnace 1 while v to be below the conveyer rod or cable 26, and may be positioned in any desired relation theret-o, but preferably the conveyer rod or cable is positioned above and a little to oneside of the furnace. Upon this rod or cable 26 travels a roller 27 from which roller 27 is suspended a lifting lever 28, by means of a chain 29. The hooks 25 are connected to the lever 28 by meansof the chain 30. It will, therefore, be Seen that when it is desired to lift the pot 17 to or from the box 1, the dovetail fillers 15 may be removed from the notches 14 so as'to permit the hooks to enter the notches 14: for lifting the pots out of the furnace by allowing the hooks 25 to engage the sockets 24:. The lever can then be operated so as to raise the pot 17 out of the box 1.

. Before the pots are set inthe furnace to be used, they are placed in a pot-arch and heated gradually until they are hot. The pots are then conveyed to and placed in the I ery hot through the medium of the lever 28, and the conveyer pulley 27. This operation may be very quickly and efiiciently carried out through the apparatus as above set forth and illustrated for the reason that the' pot may be quickly and efficiently connected. to the hooks 25 so aS to be conveyed to the furnace. It will 'be seen that as soon as the hooks 25 engage the pot' l7 sufficiently, the shaft 16 may be placed into the sockets 22 so that the pots are ready to be set into the furnace 1. From the structure illustrated'and described, it will be seen that the top of the furnace will be held in a closed position, in order to confine the heat'within the furnace, and-since the pots will fit very closely in the furnace, the heat will be prevented from coming in contact with. the shafts which support the pots 17. It will be further seen that by having the pots formed as illustrated that the pots will reverse freely in a furnace in which the walls are built in one or a single section surrounding them, or a solid continuous wall.

The body 1 is provided with an opening 31 for admitting the burner pipe or other fuel supply into the furnace below the pot 17. drain opening 32 is formed in the 34. This operating handle will hold the pots firmly in their respective positions while being used and drained by swinging the handle between the pins 35, as illustrated in F ig. 2.

It will be seen that as the pot 17 is re furnace, the top 4- may be swung upwardly for the reason that the versed within the same is connected of a chain 12.

What is claimed is l. A device of the character described comprising a furnace, a pot remoyably mounted therein, provided with a cavity at opposite ends upon opposite faces thereof, means carried by said furnace and engaging said pot for reversing the same within said furnace, whereby one of said cavities may be heated while the other cavity is being emptied, a hinged door overhanging said pot and adapted to be swung upwardly when said pot is reversed, a shoulder formed upon said pot for engaging said door and holding the same in spaced relation to that portion.of the pot extending beneath the door, and means for swinging said pot upwardly, said door being adapted to normally rest in a closed position over one end of said pot when said pot is in a horizontal position within said furnace.

2. A furnace of' the character described to the lever 10 by means comprising a frame, a door restingupqn the.

upper portion of said furnace and pieotally connected with one end thereof, a vertical strip secured to the hinged end of said door and extending. above said door, a lever pivotally connected at one end with the side of said furnace, and a flexible connection between said lever and said vertical strip for raising said door. I

In testimony whereof I hereunto aflix my signature in presence of two witnesses.
